A sea of marchers walked down Market Street in San Francisco to celebrate international workers' day. It was a peaceful event with several messages.

A small group gathered in front of San Francisco's immigration offices early Monday morning. With deportations on the rise, people here voiced their disapproval of the President's plans to keep undocumented people out of the country.

"This May Day we are making sure that all immigrant families are standing together against the deportation and detention of immigrant families," said Hong Mei Pang, who works with Chinese for Affirmative Action.

The bigger gathering was at Justin Herman Plaza where unions, immigrant advocates and regular folks called it a march for all Americans.
